EYEG LASSES OR SPECTACLES.

SPECIFICATION forming part of Letters Patent No. 683,108, datedSeptember 24, 1901.

Application filed July 1, 1901! To all whom. it may concern..-

Be it known that I, JOSEPH O. DUROUAUX, a citizen of the United States,residing at the city of St. Louis, in the State of Missouri, haveinvented a certain new and useful Improvement in Eyeglasses orSpectacles, of which the following is such a full, clear, and exactdescription as will enable anyone skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, forming part of this specification.

My invention relates to improvements in eyeglasses or spectacles, andmore particularly to straps forsccuring the frames to skeletoneyeglasses or spectacles.

One object of my invention is to provide a strap which can be adapted toany thickness of lens.

Another object of my invention is to so construct the strap that thelens will be firmly held, so that it cannot work loose on the glassscrew.

My invention consists in part in the combination, with the lens of aneyeglass or spectacle, of a clamping-plate fitting against one side ofsaid lens, a frame-supporting member carried by said clamping plate, ,a.second clamping-plate fitting against the other side of said lens, aclam pin g-screw passing through both of said clamping-plates and saidlens, and a pin connecting said clamping-plates, said pin being arrangedat one side of the clamping-screw and bearing against the edge of thelens to prevent the rotation of the same on said clamping-screw.

My invention also consists in other novel features and details ofconstruction, all of which are described in the following specificationand pointed out in the claims affixed hereto.

In the accompanying drawings, which illustrate my invention, Figure 1 isa view of a pair of eyeglasses. isometric projections showing details ofconstruction, and Fig. 4 is a view of a portion of a pair of spectacles-Like marks of reference refert-o similarcombination with a lens, of aclamping-plate parts in the several views of the drawings.

1'0 represents the lenses, to which the frames are secured by means ofthe straps. Each of the straps consists of two substantially trian-Figs. 2 and 3 are enlarged Serial No. 66,643. (No model.)

pair of eyeglasses this frain e-su pportin g mem- I her will consist ofa post 13 and box 14, in

which are secured the spring 15 and the'noseguard 16. In the case of apairot' spectacles the frame-supporting member on the clamping-plate 11at the inner end of the lens will consist in the end 17 of the bridge18. At

the outer end of the lens the frame-supportas shown in Fig. 2 of thedrawings. The pins 23 pass through corresponding openings 24 in theclamping plate 12. These pins 23 should be of such length that they willpass through the plate 12 when the thickest lenses are used. W'henthinner lenses are used, the ends of the pins 23 may be filed off flushwith the face of the clamping-plate 12 after the.

plates have been secured in position by means of the glass-screw 21.

It will be seen that with my strap a lens of any thickness can be used,and at the same time the lens is firmly held between the clamping-platesand prevented from rotating on the screw 21 by means of the pins 23.

I am aware that straps for skeleton eyeglasses and spectacles havebeen'heretofore made in which but a single clamping-plate was used,which clampingplate was provided with an arm adapted to come in contactwith a finger carried on a washer at the opposite side of the lens, andtherefore do not claim such construction.

Having fully described my invention,what

I claim as new, and desire to secure byLetters Patent of the UnitedStates, is

1. In a pair of eyeglasses or spectacles, the

the other side of said lens, a clamping-screw passingthrough both ofsaid c1a1nping-plates and said l'ens,and a pin connecting saidclamping-plates, said pin being situated at one side of saidclamping-screw and bearing against the edge of the lens to prevent therotation of the same on said clampingscrew.

2. In a pair of eyeglasses or spectacles, the

. combination with a lens, of a clamping-plate fitting against one sideof said lens, a framesnpporting member carried by said clamping-plate, asecond clamping-plate fitting on the other side of said lens, aclamping-screw passing through both of said clamping-plates and saidlens, and a pin rigidly carried by one of said clamping-plates andpassing freely through an opening in the other of said plates, said pinbeing situated at one side of the clamping-screw and bearing against theedge of the lens to prevent the rotation of the same on saidclamping-screw.

In a pair of eyeglasses or spectacles, the combination with a lens, of aclamping-plate fitting against one side of said lens, a framesupportingmember carried by said clamping-plate, a second clamping-plate fittingon the other side of said lens, a clamping-screw passing through both ofsaid clamping-plates and said lens, and a pair of pins connecting saidclamping-plates, one of said pins being situated at each side of theclamping-screw and bearing against the edge of the lens to prevent therotation of the same on said clamping-screw.-

4. In a pair of eyeglasses or spectacles, the combination with a lens,of a clamping-plate fitting against one side of said lens, aframesnpporting member carried by said clamping-plate, a secondclampingplate fitting against the other side of said lens, aclamping-screw passing through both of said clamping-plates and saidlens, and a pair of pins rigidly carried by one of said clamping'platesand passing freely through openings in the other of said plates, one ofsaid pins being situated at each side of the clamping-screw and bearingagainst the edge of the lens to prevent the rotation of the same on saidclamping-screw.

In testimony whereof I have hereunto set my hand and affixed my seal inthe presence of thetwo subscribing witnesses.
